Please help; I am a 3rd year engineering student starting my final project. I am looking at the effects of induced drag over an aerofoil. This is my problem starts; I have been using creo elements for the past 2 years now all programs I need to use requires catia CAD models (using v5r21). I have never used catia before and I am currently trying to self-study the tutorials and learn myself.
What I have already worked out myself.
I have gotten aerofoil co-ordinates from a website generator
Generated aerofoil with “GSD_PointSplineLoftFromExcel”
Problem 1 – using GSD_PointSplineLoftFromExcel – points macro
Using just points – not able to link points with any drawing line to produce initial aerofoil shape; therefore not able to extrude into basic wing shape. (Picture 1)
Problem 2 – using GSD_PointSplineLoftFromExcel – spline macro
Using spline option, - spline lines do not go from point to point, Picture 2 shows what I am on about.
Once I have done this then I make the basic wing shape then create wing tip aerofoils and attach to the basic wing.
Am I doing this right or does anybody know a better way to do this.
Thank you for your help and reading this.
